Here's a look at the players involved in the Mariners-Orioles trade:

Coming to the Mariners

Erik Bedard, LHP

X Bedard, who'll be 29 on March 5, was one of the most coveted pitching targets this offseason as the Orioles saw him as an opportunity to acquire several prospects. The Mariners see him as their No. 1 starter and the piece that will make them bona-fide contenders in the American League West. Bedard won't be a free agent until after the 2009 season but, because he's eligible for arbitration, the Mariners will try to work out a new contract. Bedard has requested $8 million for 2008 while the Orioles offered $6 million, and now the Mariners assume the risk of arbitration. His career statistics:

Going to the Orioles

Adam Jones, OF

Jones, 22, has been considered a future star since the Mariners drafted him in the first round in 2003. He came up as a shortstop but was converted to center field two years ago, and he would have been the Mariners' starting right fielder in 2008. Jones played briefly in each of the past two seasons with the Mariners, batting a combined .230 with three home runs and 12 RBI. His career statistics:

Sherrill, 30, became a go-to reliever the past two seasons and, because he hides the ball well, has a deceptive delivery that's difficult on left-handers. Scout Charley Kerfeld signed Sherrill out of the independent leagues in 2003 and he developed into one of baseball's best left-handed relief specialists. The Orioles may use him to close games. His career statistics

W L ERA Best season

10-8 3.65 2.36 ERA in 2007, holding left-handers to a .156 average

Chris Tillman, RHP

Tillman, 19, is a 6-foot-5 right-hander who climbed quickly in the M's minor league system the past two years. He was the organization's minor league pitcher of the year in 2007 after being promoted from low-A Wisconsin to high-A Inland Empire, where his six victories tied for the team high. He also led Inland Empire with 105 strikeouts. His career statistics:

W L ERA Best season*

10 14 4.92 7-11 in 2007 with 139 strikeouts in 135 2/3 innings at Class A Wisconsin and Inland Empire

Kam Mickolio, RHP

Mickolio, 23, climbed quickly after being drafted in 2006, going from Class A Everett his first season to Class AAA Tacoma in 2007. He pitched 19 straight scoreless innings, with 22 strikeouts, early last season at Class AA West Tennessee before being promoted to Tacoma. His career statistics:

Butler, 20, overcame two stints on the disabled list in 2007 because of a strained forearm, finishing 4-7 with a 4.75 ERA at low-A Wisconsin. He made nine starts at Class A Everett in 2006, allowing three runs or less in each of them. His career statistics:
